Prices shown in currencies other than USA Dollars are estimates based on current exchange rates. We will charge your credit card in USA Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.
Shipments outside the USA are declared as “bike parts” for customs purposes and will include the actual amount paid for merchandise and shipping. Jenson USA will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.
Downhill bikes benefit from small gear ranges with even gear-progression throughout the cassette. Paired with a clutch rear derailleur this maintains proper tension on the chain and less slack when going through rough terrain, eliminating double or triple shifts. The OneUp Components DH Block allows you to reap all the benefits of 6 or 7-speed DH specific drivetrain without having to drop hundreds of dollars on a cassette and driver body. Convert your 9, 10, or 11 speed SRAM or Shimano cassette to work seamlessly with your clutch-enable DH bike, providing smooth and responsive shifting for a fraction of the cost. Depending on the base cassette, the DH Block allows you to create a 6 or 7 speed DH specific cassette with a 2 tooth progression through the majority of the cassette, creating a super smooth 11-25T or 11-21T cassette that you can shift through in only 2 full shifts.

After installing the DH Block onto your cassette, you will need to setup your rear derailleur. (See compatibility guide for full list)
Please Note: The DH Block was designed primarily to work with Shimano 10 speed and SRAM X01DH drivetrains. Due to the low limit screw geometry on 10spd SRAM and all 9spd setups, you will need to follow the Alternative Method setup instructions. This will leave 3 additional clicks remaining on the shifter when in the hightest gear (11T).
